Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a step for getting on and off a large cab-over type truck or the like.

[Prior Art] As shown in FIG. 1, in a cab-over type vehicle, a cab is arranged above a front wheel 10, a headlight 3 is attached to the front of the cab, and a bumper 2 is attached below the cab. An ingress/egress step having tread plates 8 and 9 is located below the entrance of a door 4 that can be opened and closed about its front edge as an axis, and is fixed to the side wall of the vehicle body in front of a front wheel 10.

The tread plate 9 is surrounded by the side wall plate 12 and the front and rear end wall plates 7, and the tread plate 8 is surrounded by the side wall plate 5 and the front and rear end wall plates 6. In order to scrape off mud and snow from footwear and to prevent passengers from slipping off, each tread plate 8, 9 has vertical slits that define the slits of the tread plate, as disclosed in Japanese Utility Model Publication No. 56-46981, for example. The upper edge of the board is serrated.

However, if the treads are slatted, muddy water splashed up from the road surface by the front wheels while the vehicle is running passes through the slatted openings or slits and adheres to the side walls of the vehicle body (for example, the outer panels of the doors). . Furthermore, if the footboards are slatted, mud adhering to the footboards may be blown up by the wind pressure from the underside of the vehicle while the vehicle is running, and may adhere to the outer panels of the doors.

In order to prevent muddy water etc. from blowing up from the slits as described above, openings in the slat-shaped treads are disclosed in, for example, Japanese Utility Model Application No. 56-111080 and Japanese Utility Model Application No. 58-100843. In addition, there have been proposals for systems that are equipped with a divided shielding plate to prevent mud from splashing, or systems that are equipped with a cover that closes the bottom surface of the tread, but the structure is complicated and press molding is difficult and costs increase.

[Problems to be Solved by the Invention] An object of the invention is to provide a step for getting on and off a vehicle that is easy to manufacture and can prevent muddy water from splashing up from the slits in the tread.

[Means for solving the problem] In order to achieve the above object, the configuration of the present invention connects a sloped wall that slopes downward toward the vehicle body to the tip edge of the tread that is located in front of the front wheels and is supported by the side wall of the vehicle body. , an end wall plate is connected to the front and rear ends of a cavity surrounded by a tread having a slit and an inclined wall, and a flexible cover is suspended from the base edge of the tread to close the cavity.

[Operation] The plurality of tread plates 33, 35 are press-molded from a thick plate integrally with the inclined wall 34 that slopes downward from the leading edge toward the vehicle body. Slits 32 are provided in the footboards 33 and 35, and are used to remove mud from footwear. Mud is stepping board 3
3 and the sloping wall 34.
The front and rear ends of the empty space 24 are closed by end wall plates 38, and the vehicle body side is closed by a flexible cover 40 made of rubber or the like, thereby preventing mud and snow from blowing up due to wind blowing while the vehicle is running. Ru.

[Embodiment of the invention] As shown in FIG. 2, the getting-on/off step according to the invention consists of a pair of front and rear mounting frames 21 and a wall plate 30 coupled to the mounting frames 21. The mounting frame 21 has one side edge 23
is bent toward the front of the vehicle body, and the other side edge portion 22 is bent toward the rear of the vehicle body.

A triangular protruding wall plate 29 that supports a tread plate 33 by bending the side edge 22 is integrally formed at the upper and lower intermediate portions of the mounting frame 21, and a protruding wall plate 25 that supports a tread plate 35 is integrally formed at the lower end. be done. Projection wall board 29,2
Shelf edges 27 and 28 are formed by bending the upper edges of 5. The mounting frame 21 is constructed symmetrically in the front and rear, and is fixed to the outer wall of the vehicle body by suitable means.

The wall plate 30 coupled to the mounting frame 21 is formed by bending a plate of a predetermined width to provide an inclined wall 31 on the upper side, and a vertical wall portion 36 that is sequentially overlapped with the side edge portion 22 of the mounting frame 21 downward. Step board 33 superimposed on shelf edge 27
Then, fold back from the tip edge of the treadle 33 and attach the mounting frame 21.
The inclined wall 34 surrounding the projecting wall plate 29 and the mounting frame 2
a vertical wall portion 37 overlaid on the side edge portion 22 of 1;
A tread plate 35 is configured to overlap the shelf edge 28 of the projecting wall board 25. A slit 32 is provided in each of the footboards 33 and 35.

In order to prevent muddy water from jumping up from the slits 32 of the footboard 33, spacers 42 are connected to the side edges 22 of the pair of front and rear mounting frames 21. The edges are suspended by bolts 41.

In the present invention, an inclined wall 34 is provided that slopes downward toward the vehicle body from the tip edge of the treadle 33 (the edge away from the side wall of the vehicle body), and the front and rear ends of the empty space 24 surrounded by the treadle 33 and the inclined wall 34 are End wall plate or projecting wall plate 29
Closed by. The vehicle body side of the cavity 24 is closed by a flexible cover 40 made of rubber or the like.

Therefore, according to the above-mentioned configuration, the hollow portion 24 includes the projecting wall plates 29 as the front and rear end wall plates, and the inclined wall 34.
and the flexible cover 40,
There is no room for air to enter from the outside, and even if air tries to enter, the flexible cover 40 will block the side edge 2 of the mounting frame.
2, and the empty part 24 is attached to the slit 3 of the footboard 33.
It is only opened to the outside through 2.

The mud and snow scraped off by the slits 32 are retained in the empty space 24. To remove mud and snow, stop the vehicle and push open the flexible cover 40 to scrape it out, or push the scraper through the slit 32 to push open the flexible cover 40 and remove the mud and snow directly onto the road. Fall.

While driving, as mentioned above, no wind blows into the empty space 24 from below, so problems such as mud, etc. retained in the empty area 24 blowing up from the slits 32 and adhering to the outer panel of the door are completely avoided. is prevented.

Note that even if the sloped wall 34 is not provided on the lower side of the treadle 35, even if mud from the treadle 35 is blown up by the wind passing through the slit 32 from the bottom of the vehicle body, the upper sloped wall 34 will suppress the problem. There is no.

In the embodiment shown in FIG. 3, without using the mounting frame 21, the flange 3 of the wall plate 30 is placed between a pair of front and rear end wall plates 38 having approximately the same width as the tread width of the tread plates 33, 35.
9 and connect the hollow portion 24 to the vertical wall portion 36 of the wall plate 30.
A flexible cover 40 that closes the back of the body is suspended.

[Effects of the invention] As described above, the present invention connects the tip edge of the tread that is located in front of the front wheels and is supported by the side wall of the vehicle body with a slanted wall that slopes downward toward the vehicle body. End wall plates are connected to the front and rear ends of the enclosed space, and a flexible cover is suspended from the base edge of the tread to close the space, and the space is integrally connected to the tread from the leading edge to the vehicle body side. The slits for the tread and the slanted wall that slope downward are press-formed from a single thick plate, making processing and assembly easy. Since the board closes off the vehicle body side with a flexible cover, wind blowing into the empty space while the vehicle is running is suppressed.
Therefore, problems such as mud and snow in the empty space being blown up through the slits and adhering to the outer panel of the door are eliminated.
